Title: Fuel injection system
Inventor: REMBOLD HELMUT DIPL ING
IPC: F02M69/00
Filed: 1981-04-07
Abstract: A fuel injection system is proposed which serves for the metering of a quantity of fuel adjusted to the intake air quantity and for controlling the fuel-air mixture as a function of operating characteristics of the internal combustion engine. The fuel injection system comprises an air flow measuring element (2) and downstream of a throttle valve (3) a compressor (6) for compressing the air fed to the internal combustion engine (5). A fuel injection valve (10), by way of which at least some of the fuel quantity intended for injection is injected into the compressor (6), is arranged on the compressor (6), as a result of which the fuel undergoes a very good preparation and, on the other hand, owing to the required vaporisation heat, causes cooling of the compressor and contributes to its lubrication. The fuel injection valve (10) on the compressor (6) can also be used for the feeding of additional fuel whilst the normal fuel quantity is injected by way of individual fuel injection valves (21) into the individual intake pipes (7) immediately upstream of the inlet valves of each cylinder of the internal combustion engine (5). <IMAGE>

Title: Measuring and control device for the tension of flexible drives such as V-belt drives
Inventor: SINGER MANFRED
IPC: G01L5/06
Filed: 1981-07-18
Abstract: The invention relates to a measuring and control device for the tension of flexible drives such as V-belt drives for driving heavy loads. The device ensures the tractive power (force) and signals the operating state for the readjustment in a simple way. A flexible helical-spring coupling (9) is installed for this purpose between a conventional retightening spindle (7) of a motor rocker arm (5) and the support point of this spindle, for example the motor stand or the abutment (8). The magnitude of the spring biasing is tuned to the V-belt drive. Even in the event of being lengthened, the V-belt drive is held by means of the tension spring (12) at the tension required for the torque. The belt lengthening is indicated by longitudinal displacement of a pressure piece (member) (11) with respect to the flexible helical-spring coupling (9). A remote display is possible with the aid of mechanical, hydraulic or electric means (19 to 24). <IMAGE>

Title: Method and cutter for producing boat-shaped wooden patches and matching cutouts in wooden parts to be repaired
Inventor: VETTER GUENTHER
IPC: B27M3/00
Filed: 1981-10-10
Abstract: The method for producing boat-shaped wooden patches and matching cutouts in wooden parts to be repaired consists in first producing the wooden patches with the aid of a face cutter. Using the face cutter a workpiece is cut so that a curved cutout base results which is severed from the workpiece along a plane. This results in a small piece with a curve provided on one side. This small piece can be cut up by severing cuts into boat-shaped wooden patches. Cutouts, which correspond in their shape and in their dimensions to the boat-shaped wooden patches, are produced in the wooden part to be repaired at the damaged points by means of a grooving cutter. The repair takes place by inserting the wooden patches into these cutouts. The cutters used to carry out the method can have cutting edges extending in a circular arc; the cutting edges can, however, also form a straight line rising towards the median axis of the cutter.
